While the area is a known location for lithium-bearing pegmatites, the geology at the Lake Johnston project is poorly understood, as much of the tenure has been mapped as granite.
Zones of greenstones have been intersected in historical drilling and KNG believes there’s potential for mafics, ultramafics and sediments to be faulted into the granites.
KNG is on a mission to delineate high-grade pegmatites hosted in lithium mineralisation at Lake Johnson, with the soil sampling survey successfully turning up assays of +200ppm over an area of 6.5km x 3km.
The anomaly is open to the north and south and based on this initial success.
KNG now plans to extend the soil sampling program to cover the recently acquired ground directly to the north of E63/2068.
This additional tenement increases the size of the company’s Lake Johnston tenure to 770km2.
“These results show there is clearly huge lithium potential at Lake Johnston,” KNG managing director Richard Maddocks says.
“We had strong evidence for the presence of pegmatites and lithium from sampling historic drill holes and this recent soil sampling program confirms the presence of a significant, extensive high-grade lithium anomaly in soils.
“In light of these outstanding results and the potential for pegmatite-hosted lithium mineralisation, we plan to define drill targets through soil sampling to identify the highest-grade areas.”
